Breno undergoes knee surgery

Bayern Munich defender Breno underwent surgery on Thursday at a clinic in Augsburg after he suffered a recurrence of inflammation in his right knee, the Bundesliga outfit announced on Friday.

"We can't say for some time how long Breno will be unavailable," club doctor Hans-Wilhelm Mueller-Wohlfahrt said on the team's website.

The 22-year-old Brazilian has only played for Bayern 13 times since his arrival from Sao Paulo in the summer of 2010.

Breno had a brush with German law earlier this season after being suspected of setting his house on fire in September and his behaviour has been a cause for concern for the Bavarian giants.
